Description

Technical Field

[0001] This utility model relates to the field of military training equipment, specifically a throttle and instrument linkage device for armored vehicle simulation training. Background Technology

[0002] The throttle control system of a real vehicle is used to control the power output of the vehicle's engine. Its structure and transmission system are relatively complex and cannot be applied to simulation training equipment. The throttle and instrument linkage device used for armored vehicle simulation training is designed to mimic the throttle control system of a real vehicle, requiring that its appearance, operation method, and force feel be basically consistent with the real vehicle throttle control system.

[0003] However, the rotation angle and operating force of the traditional simulator throttle control device are quite different from those of the real vehicle. In addition, the structure is easily damaged, prone to jamming, and has poor reliability, which cannot guarantee that the troops can carry out long-term, high-frequency operation training.

[0004] In view of the above, in order to overcome the above technical problems, this utility model designs a throttle and instrument linkage device for armored vehicle simulation training, which solves the above technical problems. Summary of the Invention

[0005] The technical objective of this invention is to convert the rotational motion of the foot accelerator into the linear displacement of the wire rope by using a steel wire rope as a connecting link, and then convert the linear displacement into the rotational motion of the hand accelerator and the tachometer, thereby realizing the conversion of motion forms; thus enabling the pedal, hand accelerator lever and tachometer to be linked together, making the simulation training more realistic.

[0006] To achieve the above-mentioned technical objectives, this utility model provides the following technical solution:

[0007] This utility model provides a throttle and instrument linkage device for armored vehicle simulation training, including a throttle pedal; the throttle pedal can be pressed by the trainee to simulate the throttle pedal in driving; it also includes a linkage mechanism, a hand throttle mechanism and an instrument unit; the linkage mechanism is used to link the trainee's action of pressing the throttle pedal and the action of flicking the hand throttle lever, and at the same time it will cause the instrument unit to operate, thereby simulating the throttle instrument by rotating the pointer.

[0008] The accelerator pedal is connected to the linkage mechanism via a connecting crank. An adjusting bolt is installed on the connecting crank. The lower end of the adjusting bolt contacts the bottom of the vehicle body as the connecting crank rotates, thereby limiting the travel of the accelerator pedal.

[0009] Furthermore, by adjusting the length of the adjusting bolt, the rotation angle of the connecting crank rod is changed. Specifically, by changing the downward extension length of the adjusting bolt, the pedal travel of the accelerator pedal is changed, thereby simulating the pedal feel of different vehicles.

[0010] The linkage mechanism is connected to an instrument wire and a throttle wire; the instrument wire and the throttle wire can be used to connect various mechanisms over long distances, making the linkage response between mechanisms faster.

[0011] The linkage mechanism is connected to the instrument unit via the instrument wire, thereby causing the linkage mechanism to pull the instrument wire and rotate the pointer in the instrument unit by a corresponding angle, thus simulating the instrument indication of the throttle.

[0012] The linkage mechanism is also connected to the hand throttle mechanism via the hand throttle cable, thereby enabling the accelerator pedal and the hand throttle mechanism to work together to simulate a real driving environment. The trainee can operate the accelerator via the hand throttle mechanism or by foot, and both actions are synchronized within the instrument unit. The linkage mechanism, through the rotation of the accelerator pedal, pulls the instrument cable and, simultaneously, through the hand throttle mechanism, pulls the hand throttle cable to activate the linkage mechanism.

[0013] Specifically, the linkage mechanism includes a linkage shaft, an instrument traction arm, a throttle traction arm, a shaft support, a pedal return spring, and a spring connecting plate. The linkage shaft is equipped with the instrument traction arm and the throttle traction arm. The linkage shaft is rotatably mounted on the vehicle body base via the shaft support. The linkage shaft enables the instrument traction arm and the throttle traction arm to rotate, that is, the pressing motion of the accelerator pedal is converted into the rotational motion of the connecting crank, which in turn drives the linkage shaft to rotate, thereby realizing the rotation of the instrument traction arm and the throttle traction arm.

[0014] One end of the pedal return spring is connected to the lower end of the hand throttle traction arm, and the other end is installed inside the vehicle body through a spring connecting plate. The pedal return spring is used to reset the accelerator pedal. When the trainee releases the foot, the pedal return spring resets, which in turn pulls the hand throttle traction arm to rotate, thereby causing the linkage shaft to reset and the accelerator pedal to reset.

[0015] One end of the instrument wire and the throttle wire are respectively connected to the instrument traction arm and the throttle traction arm; the other end of the instrument wire and the throttle wire are respectively connected to the instrument unit and the throttle mechanism; the linkage shaft tightens the instrument wire and loosens the throttle wire by rotating the instrument traction arm and the throttle traction arm respectively.

[0016] When the trainee presses the accelerator pedal, the linkage shaft rotates, driving the instrument traction arm to tighten the instrument cable, thereby moving the pointer on the instrument unit to simulate an increase in engine speed. Simultaneously, one end of the hand throttle cable is connected to the hand throttle traction arm, and the other end to the hand throttle mechanism. As the linkage shaft rotates, the hand throttle traction arm releases the hand throttle cable. Then, the trainee pulls down the accelerator lever, pulling the hand throttle cable back to a taut state, thus maintaining the accelerator pedal in a throttle-assisted state, simulating the constant speed cruise of an armored vehicle.

[0017] The instrument traction arm and the throttle traction arm are installed at offset positions in both the normal and axial directions of the linkage shaft. By installing the instrument traction arm and the throttle traction arm at different positions on the linkage shaft, they will not collide or interfere with each other during rotation, thus improving the stability and reliability of the device.

[0018] The staggered installation allows the instrument traction arm and the throttle traction arm to independently control their respective steel cables (instrument steel cable and throttle steel cable) under the action of the linkage shaft, thereby enabling the separate tightening or loosening of different steel cables, so that the actions of the instrument and the throttle can be precisely responded to according to the operation of the accelerator pedal.

[0019] The end of the instrument wire connected to the instrument traction arm is at a 180° angle to the rotation direction of the instrument traction arm. The 180° connection angle between the instrument wire and the instrument traction arm means that when the traction arm rotates, the wire can obtain the maximum tension, ensuring that when the accelerator pedal is pressed, the instrument wire can efficiently and accurately pull the instrument pointer, so that it accurately reflects the change in engine speed.

[0020] The end of the throttle cable connected to the throttle traction arm is at 0° to the rotation direction of the throttle traction arm, i.e., it is in the same direction as the rotation. This design ensures that the throttle cable is not tightened when the linkage shaft rotates, but remains slack, thereby avoiding interference with the throttle position due to accelerator pedal operation and ensuring that the throttle remains in its original position when not actively operated.

[0021] The instrument unit includes a pinion shaft, a pointer, a small shaft, a sector gear, a support arm, and a return spring. The pinion shaft is synchronously connected to the pointer, ensuring that the rotation of the pinion shaft can directly drive the pointer and provide a clear speed or rotation speed display.

[0022] The hand throttle mechanism includes a hand accelerator lever, a locking component, a stop shaft, a hand throttle pivot, and a pivot arm; the hand throttle pivot is fixedly mounted on the vehicle body, and the hand accelerator lever and the pivot arm are both rotatably mounted on the hand throttle pivot and do not interfere with each other.

[0023] The hand accelerator lever and the rotating arm are respectively mounted on the same rotating shaft. The stop shaft is mounted on the hand accelerator lever, and one end of the rotating arm is in close contact with the lower part of the stop shaft without gaps. The other end of the rotating arm is connected to the hand accelerator cable. This design ensures that the hand accelerator lever can be controlled independently without being affected by the movement of the rotating arm (i.e., the movement of the foot accelerator). At the same time, the hand accelerator lever can drive the rotating arm to rotate synchronously through the stop shaft, and then control the accelerator pedal's throttle application state through the hand accelerator cable.

[0024] The locking component is installed on the hand accelerator lever to fix its position and prevent accidental displacement, thereby keeping the hand accelerator in the set position to stabilize the simulated speed of the vehicle.

[0025] The locking assembly includes a pawl and an arc-shaped toothed plate; the arc-shaped toothed plate is fixedly mounted on the vehicle body and has serrations at its apex, which can lock the hook at one end of the pawl. The pawl is rotatably mounted on the throttle lever, thereby locking the throttle lever when it is rotated downwards.

[0026] The upper end of the hand-operated oiling lever is retractable and connected to one end of the pawl. The middle part of the pawl is rotatably mounted on the front of the middle part of the hand-operated oiling lever, thereby forming an adjustment lever for the pawl. That is, the upper retractable section of the hand-operated oiling lever and the rear end of the pawl are the adjustment ends of the lever. The lower main body section of the hand-operated oiling lever is rotatably mounted on the middle part of the pawl. Thus, the front end hook of the pawl can be lifted under the pressure of the adjustment end, thereby unlocking the front end hook of the pawl from the arc-shaped plate teeth.

[0027] An adjusting bolt is installed on the connecting crank, which is used to limit the rotation angle of the connecting crank.

[0028] Both the instrument cable and the throttle cable are conducted through a steel wire plastic tube installed inside the vehicle body, and both ends of the steel wire plastic tube are equipped with hollow steel wire joints.

[0029] The beneficial effects of this utility model are as follows:

[0030] 1. This utility model provides a throttle and instrument linkage device for armored vehicle simulation training. The operating force and rotation angle of this device are basically consistent with the transmission control device of the actual vehicle. By calculating and reasonably selecting the rotation radius of each operating component and selecting an appropriate gear transmission ratio, the rotation angle ratio of the foot throttle, hand throttle, and tachometer is made consistent, realizing the quantitative conversion of motion. Thus, it simulates driving throttle training operation and is suitable for the throttle operation training needs of various types of vehicles with the same chassis in driving simulators.

[0031] 2. The throttle and instrument linkage device for armored vehicle simulation training provided by this utility model can realize the linkage relationship of each component through mechanical means only. It is low in cost, highly reliable, and can be widely used in simple driving simulator equipment of the military. Attached Figure Description

[0040] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0041] like Figure 1As shown, the present invention provides a throttle and instrument linkage device for armored vehicle simulation training, including a throttle pedal 1; the throttle pedal 1 can be stepped on by the trainee to simulate the throttle foot pedal in driving; it also includes a linkage mechanism 3, a hand throttle mechanism 4 and an instrument unit 5;

[0042] The accelerator pedal 1 is connected to the linkage mechanism 3 via the connecting crank 2. The linkage mechanism 3 is connected to the instrument cable 6 and the hand throttle cable 7. The linkage mechanism 3 is connected to the instrument unit 5 via the instrument cable 6 and to the hand throttle mechanism 4 via the hand throttle cable 7. The linkage mechanism 3 is linked by the rotation caused by the accelerator pedal 1, which in turn pulls the instrument cable 6 and the hand throttle cable 7 via the hand throttle mechanism 4.

[0043] like Figure 2 and Figure 3 As shown, the linkage mechanism 3 includes a linkage shaft 31, an instrument traction arm 32, a hand throttle traction arm 33, a shaft support 34, a pedal return spring 35, and a spring connecting plate 36; the throttle pedal 1, the connecting crank 2, the instrument traction arm 32, and the hand throttle traction arm 33 are all welded to the linkage shaft 31; the linkage shaft 31 is rotatably mounted on the vehicle body base through the shaft support 34, and both ends of the linkage shaft 31 are supported by the shaft support 34, allowing it to rotate freely, and are connected to the vehicle body base by bolts.

[0044] like Figure 3 As shown, one end of the pedal return spring 35 is connected to the lower end of the hand throttle traction arm 33, and the other end is installed inside the vehicle body through the spring connecting plate 36. Specifically, the spring connecting plate 36 and the hand throttle traction arm 33 are connected by the pedal return spring 35 and the hinge bolt.

[0045] like Figure 2 and Figure 3 As shown, the instrument traction arm 32 and the hand throttle traction arm 33 are installed at offset positions in both the normal and axial directions of the linkage shaft 31.

[0046] like Figure 2 and Figure 3 As shown in the initial state, the end of the instrument cable 6 connected to the instrument traction arm 32 is vertically collinear with the rotation direction of the instrument traction arm 32, and the end of the hand throttle cable 7 connected to the hand throttle traction arm 33 is horizontally collinear with the rotation direction of the hand throttle traction arm 33.

[0047] like Figure 3-5As shown, the instrument unit 5 includes a pinion shaft 51, a pointer 54, a small shaft 55, a sector gear 56, a support arm 62, and a return spring 63. The pinion shaft 51 passes through the instrument base plate 52 and the instrument panel 53 (with scale lines and other patterns printed on it) and is riveted to the pointer 54. One end of the small shaft 55 is inserted into the instrument base plate 52, and the other end is connected to the sector gear 56 and the liner 57, so that the sector gear 56 meshes with the pinion shaft 51.

[0048] A sector gear 56 is rotatably mounted inside the instrument unit 5 via a small shaft 55. An instrument wire 6 is connected to the non-gear end of the sector gear 56, and the gear end of the sector gear 56 meshes with the pinion shaft 51. When the accelerator pedal 1 is depressed, the instrument wire 6 is tightened, causing the sector gear 56 to rotate around the small shaft 55. Through gear meshing, the pinion shaft 51 rotates accordingly, thereby driving the pointer 54 to display the corresponding speed, achieving simulated speed indication.

[0049] The support arm 62 is fixedly installed inside the instrument unit 5 and connected to the sector gear 56 via a return spring 63. The return spring 63 ensures that the sector gear 56 returns to its original position after the accelerator pedal 1 is released, simultaneously driving the pinion shaft 51 and the gauge needle 54 back to their initial positions. This increases the reliability of the device, enabling the instrument to accurately reflect changes in throttle operation.

[0050] like Figure 4 and Figure 5 As shown, the back frame 58 presses down the sector gear 56 and the pinion shaft 51, and is connected to the instrument base plate 52 by screws; the instrument case 59 contains a protective glass 60 and an elastic washer 61, and is connected to the instrument base plate 52 and the support arm 62 by screws; the return spring 63 is connected to the sector gear 56 and the support arm 62.

[0051] like Figure 2 and Figure 3 As shown, the hand throttle mechanism 4 includes a hand accelerator lever 41, a pawl 421, an arc-shaped toothed plate 45, a stop shaft 43, a hand accelerator pivot 44, and a rotating arm 46; wherein the pawl 421 and the arc-shaped toothed plate 45 are locking components 42; specifically, the hand accelerator pivot 44 is fixedly installed on the vehicle body, and the hand accelerator lever 41 and the rotating arm 46 are both rotatably installed on the hand accelerator pivot 44 and do not interfere with each other; the stop shaft 43 is installed on the hand accelerator lever 41 and is used to limit the rotation position of the upper end of the rotating arm 46; the arc-shaped toothed plate 45 is fixedly installed on the vehicle body and its arc apex is provided with serrations; the hand accelerator lever 41 is telescopic and the telescopic section is connected to one end of the pawl 421, the middle part of the pawl 421 is rotatably installed on the middle body of the hand accelerator lever 41, and the other end of the pawl 421 is hook-shaped and engages with the arc apex of the arc-shaped toothed plate 45.

[0052] like Figure 3As shown in the enlarged view, the hand throttle lever 41 and the pawl 421 are connected by a pin 422 and welded to the stop shaft 43; the hand throttle lever 41, the arc-shaped toothed plate 45, and the rotating arm 46 are connected by the hand throttle rotating shaft 44, and the arc-shaped toothed plate 45 is fixed to the frame by bolts; one end of the hand throttle steel wire 7 is connected to the rotating arm 46 by a steel wire set screw, and the other end passes through the hollow steel wire joint 9 and the steel wire plastic tube 8 fixed on the frame, and is connected to the hand throttle traction arm 33 by a steel wire set screw.

[0053] The adjusting bolt 21 is connected to the connecting crank 2 by threads, and its head contacts the frame, thereby limiting the rotation of the accelerator pedal 1. Adjusting its length can change the accelerator rotation angle.

[0054] like Figure 1-3 As shown, the instrument wire 6 and the hand throttle wire 7 are both conducted through the wire plastic tube 8 installed in the vehicle body. Both ends of the wire plastic tube 8 are equipped with hollow wire connectors 9. One end of the instrument wire 6 is connected to the instrument traction arm 32 through the wire set screw, and the other end passes through the hollow wire connector 9 and the wire plastic tube 8 fixed on the frame and is connected to the sector gear 56.

[0055] The instrument cable 6 and the throttle cable 7 should be of appropriate length and taut, so that the throttle pedal 1, the gauge needle 54, and the accelerator lever 41 are all in a taut position. Figure 3 The initial position in.

[0056] like Figure 1-5 As shown, in practical operation, when the user presses the accelerator pedal 1, the linkage shaft 31 rotates, causing the instrument traction arm 32 and the hand throttle traction arm 33 to rotate counterclockwise as shown in the figure. The instrument traction arm 32 pulls the instrument cable 6, which in turn pulls the sector gear 56 to rotate around the small shaft 55, tightening the return spring 63, and engaging with the pinion shaft 51 for gear transmission. The pinion shaft 51 drives the gauge needle 54 to rotate clockwise as shown in the figure, meaning that the speed increases as the accelerator pedal is pressed. At the same time, the hand throttle traction arm 33 tightens the pedal return spring 35.

[0057] When the trainee releases the accelerator pedal 1, the pedal return spring 35 pulls the accelerator traction arm 33, the instrument traction arm 32, and the accelerator pedal 1 to rotate clockwise as shown in the figure. The accelerator pedal 1 automatically returns to its original position. The instrument cable 6 is released and is instantly tightened by the reset spring 63, which drives the sector gear 56 to rotate, thereby driving the small gear shaft 51 that meshes with it to rotate. This causes the gauge needle 54 to rotate counterclockwise as shown in the figure, which means that the speed decreases as the accelerator is released.

[0058] When the accelerator pedal 1 is pressed, the hand throttle traction arm 33 loosens the hand throttle cable 7 by a certain length. At this time, the hand throttle lever 41 can be pressed, causing the pawl 421 to rotate around the pin 422, disengaging it from the toothed groove on the arc-shaped toothed plate 45. Then, the hand throttle lever 41 is rotated clockwise, and the stop shaft 43 on it pushes the rotating arm 46 to rotate clockwise until the hand throttle cable 7 is tightened. When the hand throttle lever 41 is stopped, its internal return spring 63 springs it back, causing the pawl 421 to rotate back and re-lock into the toothed groove on the arc-shaped toothed plate 45. The hand throttle lever 41 is locked again after rotating a certain angle. When the accelerator pedal 1 is released, it will not automatically return to its original position due to the tension of the hand throttle cable 7, but will remain in place. At the same time, the gauge needle 54 points to a certain constant speed, thus simulating the constant speed cruise state of an armored vehicle.

[0059] If the hand accelerator lever 41 is operated in the reverse direction, i.e., pressed to unlock it, and then pushed upwards, the stop shaft 43 rotates with the hand accelerator lever 41, thereby releasing the limit on the rotating arm 46. The hand accelerator traction arm 33 rotates clockwise under the action of the pedal return spring 35, thereby pulling the hand accelerator cable 7 and the instrument cable 6, thus causing the accelerator pedal 1 to reset, the rotating arm 46 to rotate counterclockwise, and the instrument needle 54 to reset. This process simulates the linkage between the foot accelerator, hand accelerator, and tachometer in an armored vehicle, thereby realizing the operation training of the accelerator control system in driving simulation training.
